I obtained the "Cylinder Head Assembly Specifications" for a BMW 325 that is leaking oil through the head gasket.
They are:
Step#1 - 22 ft-lb Step #2 - Torque angle 90 degrees Step #3 - Torque angle 90 degrees
The proper tightening sequence is also provided.
I have 3 questions:
Q.1. - Since these specs are for assembly, it would mean (I guess) that a new gasket is being used. And this might mean that the specs are not really applicable to my situation since the gasket I have has been in service for a long time. Or it might be that these specs only apply to a situation where the head is completely dissassembled. Does anyone know?????????
Q.2. - I would guess that what the specs say is that every head bolt is tightend in the proper sequence to 22 ft-lb, then 2 more sequences are performed where a quarter turn is applied to each bolt. Is that what the specs are saying????????
Q.3. Heck- what if I just tighten the bolts uniformly in the proper sequence in an effort to stop the leak???????? Would there be any great harm in that?????
Thanks in advacne.
All responses are appreciated.
